SECURING A CONFIRMATION OF A SEQUENCE OF CHARACTERS, CORRESPONDING METHOD, DEVICE AND COMPUTER PROGRAM PRODUCT

摘要

The proposed technique relates to a method for securing a confirmation of a sequence of characters (SEQ) entered by a user on an electronic data entry device comprising an unsecured processor and a secured processor. This method, implemented in the secured processor, comprises determining a processing operation to be applied to said sequence of characters (SEQ), as a function of a signal (SIG_V) representing a confirmation, by the user, of the sequence of characters (SEQ), the signal (SIG_V) representing a confirmation being delivered by a confirmation means belonging to a set comprising at least two distinct confirmation means.
